Upgrading agents in silent mode

You can upgrade agents by specifying the installation properties in a text file.

In most cases, upgrade the server before you upgrade the agents. If you are upgrading from a version before 4.8.5, you must upgrade the server to 4.8.5 or 5.0 before you upgrade the server to 6.0 or later. To ensure compatibility between your agents and the server, upgrade the agents after you upgrade the server to 4.8.5 or 5.0.

  1. From the new version of the server, download the agent installer for the new agent version.
    • To download the installer, log in to the server and click the Help icon at the upper right of any page on the server, and click Tools. Then, click IBM® UrbanCode® Deploy Agent, and download and extract the file.
    • To find the installer on the server with the command line, go to the following location, and copy the file to the target computer: installation_folder/opt/tomcat/webapps/ROOT/tools/ibm-ucd-agent-version.zip
  2. Transfer the new agent installation package to the system that hosts the agent and extract the package.
  3. Create or update the agent installation properties file.
    For more information, see Agent installation properties. When you add the below property to the new agent properties file, the installer picks up the properties from the existing agent properties file:
    locked/agent.home=current_installed_agent_path
  4. Stop the agent.
  5. Run the installation file with the install-agent-from-file.bat command on Windows™ or the ./install-agent-from-file.sh command on Linux™. Provide the properties file as a command-line argument.
    On Windows, if the properties file is named install.properties, type the following command:
    install-agent-from-file install.properties
  6. Restart the agent.
On the server, click Resources > Agents and verify that the agent shows the new version.
